Louis Walsh has admitted that he does not know if he has a long-term future with The X Factor.

The Irish judge revealed that he does not take his position on the show for granted - as show chief Simon Cowell could decide to make further changes to the panel next year.

Speaking to The Mirror, he claimed: "I could be gone next year. Honestly, I don't know."

Walsh was sacked by Cowell in March 2007 and replaced by Brian Friedman. However, he was later asked to return after Simon realised that the panel lacked "chemistry" without him.
